Question

a solution of hydrochloric acid is labelled as 60%( m/v) .the density of the solution is 1.1 g m/l. calculate the concentration of the solution in %(m/m)

Answer 1

60g of HCl in 100ml solution

Density of the solution = 1.1g/ml

Mass of solution = Volume x Density = 100 x 1.1 = 110g

Therefore, concentration in w/w = (Mass of solute / mass of solution) x 100 = (60/110) x 100 = 54.5%

Answer 2

Hey mate, ....

it's so easy,

60g of HCL in solń of 100 ml

Density= 1.1 g/ml

mass of the solń = 100 g×1.1ml

= 110g.

Thus, (M/M)= (60/110) × 100

= 54. 54%

THANKS....
